41 \class QMdiArea-
42 \brief The QMdiArea widget provides an area in which MDI windows are displayed.-
43 \since 4.3-
44 \ingroup mainwindow-classes-
45 \inmodule QtWidgets-
46-
47 QMdiArea functions, essentially, like a window manager for MDI-
48 windows. For instance, it draws the windows it manages on itself-
49 and arranges them in a cascading or tile pattern. QMdiArea is-
50 commonly used as the center widget in a QMainWindow to create MDI-
51 applications, but can also be placed in any layout. The following-
52 code adds an area to a main window:-
53-
54 \snippet mdiareasnippets.cpp 0-
55-
56 Unlike the window managers for top-level windows, all window flags-
57 (Qt::WindowFlags) are supported by QMdiArea as long as the flags-
58 are supported by the current widget style. If a specific flag is-
59 not supported by the style (e.g., the-
60 \l{Qt::}{WindowShadeButtonHint}), you can still shade the window-
61 with showShaded().-
62-
63 Subwindows in QMdiArea are instances of QMdiSubWindow. They-
64 are added to an MDI area with addSubWindow(). It is common to pass-
65 a QWidget, which is set as the internal widget, to this function,-
66 but it is also possible to pass a QMdiSubWindow directly.The class-
67 inherits QWidget, and you can use the same API as with a normal-
68 top-level window when programming. QMdiSubWindow also has behavior-
69 that is specific to MDI windows. See the QMdiSubWindow class-
70 description for more details.-
71-
72 A subwindow becomes active when it gets the keyboard focus, or-
73 when setFocus() is called. The user activates a window by moving-
74 focus in the usual ways. The MDI area emits the-
75 subWindowActivated() signal when the active window changes, and-
76 the activeSubWindow() function returns the active subwindow.-
77-
78 The convenience function subWindowList() returns a list of all-
79 subwindows. This information could be used in a popup menu-
80 containing a list of windows, for example.-
81-
82 The subwindows are sorted by the current-
83 \l{QMdiArea::}{WindowOrder}. This is used for the subWindowList()-
84 and for activateNextSubWindow() and activatePreviousSubWindow().-
85 Also, it is used when cascading or tiling the windows with-
86 cascadeSubWindows() and tileSubWindows().-
87-
88 QMdiArea provides two built-in layout strategies for-
89 subwindows: cascadeSubWindows() and tileSubWindows(). Both are-
90 slots and are easily connected to menu entries.-

103 \fn QMdiArea::subWindowActivated(QMdiSubWindow *window)-
104-
105 QMdiArea emits this signal after \a window has been activated. When \a-
106 window is 0, QMdiArea has just deactivated its last active window, and-
107 there are no active windows on the workspace.-

119 is maximized, the default behavior is to maximize the next-
120 subwindow that is activated. Set this option if you do not want-

127 Specifies the criteria to use for ordering the list of child windows-
128 returned by subWindowList(). The functions cascadeSubWindows() and-

132 their creation.-

135 which they are stacked, with the top-most window being last in-
136 the list.-
